1-3. Hybrid system
There are air intake vents under the
rear seats for the purpose of cooling
the hybrid battery (traction battery). If
the vents become blocked, the hybrid
battery input and output may be
restricted, leading to a reduction in
hybrid battery (traction battery) out-
put.
When a certain level of impact is
detected by the impact sensor, the
emergency shut off system blocks the
high voltage current and stops the fuel
pump to minimize the risk of electrocu-
tion and fuel leakage. If the emergency
shut off system activates, your vehicle
will not restart. To restart the hybrid
system, contact any authorized Lexus
retailer or Lexus authorized repairer,
or any reliable repairer.
A message is automatically displayed
when a malfunction occurs in the
hybrid system or an improper opera-
tion is attempted.
If a warning message is shown on the
multi-information display, read the
NOTICE

tery) air intake vents
NOTICE
■Hybrid battery (traction battery) air intake vents
●Make sure not to block the air intake vents with anything, such as a seat cover, plastic cover, or luggage. If the
vents become blocked, the hybrid bat- tery (traction battery) input and output may be restricted, leading to a reduc-
tion in hybrid battery (traction battery) output and a malfunction.
●When dust etc. has accumulated in the air intake vents, periodically clean
them with a vacuum cleaner to prevent the vents from clogging.
●Filters are installed to the air intake vents. When the filters remain notice-
ably dirty even after cleaning the air intake vents, filter cleaning or replace-ment is recommended. When clean-
ing or replacing the filters, contact any authorized Lexus retailer or Lexus authorized repairer, or any reliable

4-6.Driving tips
When using Eco drive mode, the
torque corresponding to the accelera-
tor pedal depression amount can be
generated more smoothly than it is in
normal conditions. In addition, the
operation of the air conditioning sys-
tem (heating/cooling) will be mini-
mized, improving the fuel economy.
( P.242)
The Eco-friendly driving is possible by
keeping the indicate of Hybrid System
Indicator within Eco area. ( P.86)
Shift the shift position to D when
stopped at a traffic light, or driving in
heavy traffic etc. Shift the shift position
to P when parking. When using the N
position, there is no positive effect on
fuel consumption. In the N position, the
gasoline engine operates but electric-
ity cannot be generated. Also, when
using the air conditioning system, etc.,
the hybrid battery (traction battery)
power is consumed.
 Drive your vehicle smoothly. Avoid
abrupt acceleration and decelera-
tion. Gradual acceleration and
deceleration will make more effec-
tive use of the electric motor (trac-
tion motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration consumes
hybrid battery (traction battery)
power, resulting in poor fuel con-
sumption. Battery power can be
restored by driving with the acceler-
ator pedal slightly released.
Make sure to operate the brakes gently
and in a timely manner. A greater
amount of electrical energy can be
regenerated when slowing down.
Repeated acceleration and decelera-
tion, as well as long waits at traffic
lights, will lead to bad fuel economy.
Check traffic reports before leaving
and avoid delays as much as possible.
When driving in a traffic jam, gently
release the brake pedal to allow the
vehicle to move forward slightly while
avoiding overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.

■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning
system to the outside air mode.
●During use, various odors from inside and
outside the vehicle may enter into and accumulate in the air conditioning sys-tem. This may then cause odor to be
emitted from the vents.
●To reduce potential odors from occur-
ring: • It is recommended that the air condition-ing system be set to outside air mode
prior to turning the vehicle off. • The start timing of the blower may be delayed for a short period of time imme-
diately after the air conditioning system is started in automatic mode.
